To ZZZ-Z whom it concern. i Y

Be it known that I, WILLIAM HENRY Room-issues, of '64: Sparks street, inthe city of Uttaiva; county of Carleton, Province of Ontario, Dominionof Canada, have invented certain new and useful Improvements in Moldsfor Use in the Construction of. Concrete Buildings, of which theiolloW-ihg is spedfimioh. .7

My invention ielates to molds for use in the constiuoti'on of concretebuildings, structures and Walls of all kinds and the objects of myinvention die, to provide a. convertible and collapsible mold of thechaihct'ei described, which is economic and efficient end whiohniayreadilv be adopted to form any part of the building whdtever, to providea ih'old ihpidly which is adopted to form the Walls of the building allin one piece no mltttei how many stories may be included iii theStiildtilte; t0 plOVide 2t mold which Will fol-n1 the walls of thebolt-l ing either ;solid or hol'loW as desired and which Will p ei'in'itbf the erection of Windows, doors, eistern tanks or other buildingnecessities therein and finally to piovide a mold which Will render therooms formed thereby less susceptible to the lodgment of dust; 1

in brief. my invention oohsists of a model, comprising a series of wingswhich extend parallel With each other and ate jointed at intervals in anovel inenner' so that they may be extended to form a continuous Wall orbend zit right angles to each other to accommodate corner construction.

In the formation of hollow Wdlls it 001- la'p'silole mold isiiitrodiiced which is kept integral by the temporar ihssfooh of novellocking means; Alloi' these models are 001- I lapsible and are supportedby certain novel devices which will be hereinafter more particularlydescribed in the accom anying speeiiicdtioh zind drawings of WhichFigure 1 represents a plain View of mi improved mold as appliedtoco'rner Wall construction.

, Referring to the drawings it Will be seen that the mold initsconstruetion com rises an outer member A and an inner member B adaptedto inold the outer and inner surfed,

of the Well respectivel It will he appreelated, however, that certainfeatures of the invention might be applied to e inold insinher which isapplied to mold only one surface of a wall. Each memheooohsists of twoWall members adjustably in angular relation to each other in order thatthey ma be readil removed from the Wall of other st soothes zttter'theinolding' is epplid and the sshorets set, thus'the outer member A noth-PllSGS Wall members H end I whioh are pivotsllyr supported from aoy'llndr'ieol standard or post 10 7 As illustrated the standard istubular in form and the well members have wiping COiltdCt therewith. Theportioular form of connection illustrated between the wall member sndthestandard comprises cores 11 in the end of the standard hevingpivot pins12 at the top thereof formed with and: fitting into the threaded socketsin the cores. said pivot pins extending through hinged members 13 whichhinge members have flanges 1d whicheinbrace parallel retaining plates 15which are supported by "a spacing member 16, which] latte? may be conveniently formed of wood.

The pistes 15 fof-1n sockets in "which the elements mold the well areadaptedto be hold, these elements are conveniently in the form of lanks18 which are adapted to shut each other and may if desired have dovetailor inclined Contact With each other. These planks will vary size to suitthe nature of the stl-uoture to be molded and it will be appreciatedthat Where the mold is vsnsdhy "changing the position or the idflli ets;this'is not so important where'the mold is'used in house construction asit would be where a-concrete retaining wall or the like is beingconstructed.

The inner member B is similar'in general construction to the outermember. In order, however, to adapt bothwall elements on this member'for the molding of a perfectly straight wall the hinge members 13 havetheiriouter portions bent at angles to the radius in such a way that thewall members may beswung around into alinement with each other andhaving their outer surface extending substantially tangential to thestandard. 4 v v To provide for the formation of a hollow wall, wheredesired, a core member C may I be provided. This must necessarily be ofa collapsible character and must have a corner member of a similarcharacter.

The embodiment of the core member illustrated comprises a pair oflongitudinally extending corner guides 21 which are adapted to be spreadby a spreading member I) which has a screw threaded portion 28 adaptedto engagepartially the cylindrical screw threaded bores 23 formed inprojections 22 on the guides. It will be seen that when the pointedextremity of the tightened member is engaged with, the bores and turneditwill spread the guides and retain them in spread position.

' Spaced and parallel plates 29 are adapted if to fit the guide membersand may conwhen the rods are withdrawn.

veniently extend in recesses 24 and 27 thereon,;thevrecesses 27 beingformed at the rear of-wings 26. The plates are adapted to be releasablyheld in spaced relation by means of pairs. of lugs 34 adapted to receivelook ing rods 35, theheight of lugs being less than the normal distancebetween the plates whereby the plates may collapse together The spacebetween the plates 29is divided by means of division plates 31 securedto blocks 30 on one side of the plates. It will beiseen'that the threeplates form sockets in which wall members 33, in' the'form of'planks,may be held.--v

I After the concrete has hardened in the space l3 between the mold andcore member it is necessary to spring the same slightly to loosen theplanks from the concrete and plank on opposite sides of the core.

If it is desired to have additional support forthe sides of the moldduring casting, spacing members 36 may be provided having sharp edgeswhich contact with the surface of'thecore and wall respectively togetherwith supporting member 37 on the exteriorzwhich may be driven into orconsoaked in oil before use.

parts are thus set up the concrete 1s poured nected to the ground orfloor beneath the mold; the upper end of said supports being connectedby a tightening brace; the form of brace illustrated comprising a ring41 connected to one support and loop 38 encircling the opposite supportand a link 39 between the ring and loop and including a turn-buckle 40.It is of course obvious that if desired this additional supporting meansmight be omitted. YVhen the mold is to be used for molding a completehouse it will be necessary to provide means for the windows and doorsand these are of similar construction.

In Figs. 8 to 11, I have shown a form of mold adaptable for a window.This mold comprises the side plates 46 forming sockets 4:7 to receivethe planks 48; said plates being retained in position by means ofspacing 1 plates 51 adapted to mold the inner surface of the sides ofthe window or door opening and straps 55 having turned ends to engagethe outer surface of the plates 46 on opposite sides of the wall, saidstraps being formed with eyes 56 through which locked bolts 53 mayextend. These bolts also serve to retain the ends of the core mold inspaced relation the plates 29 of the core mold being formed with eyes toreceive the bolts. The outer ends of the straps are also formed withperforations through which bolts 50 extend into planks 49 provided onthe plates 46. It will be seen that when the bolts 50 and 53 areloosened the walls of the window molds may be collapsed and the top ofthe window mold is adapted to be formed by a member 57 and the bottom bymeans of a collapsible wedge member 58. this wedge member consists oftwo parts 60 and 61 separated a short distance by screws 62 j of themolds from adhesion of concrete oiled paper 12 or similar material maybe placed against the same. The boards used in the forms of the moldmembers are desirably When the various in and allowed to set. Before thesetting is complete any spacing members 36 which have been inserted aretilted slightly and withdrawn. After setting, the wall members areloosened and those on the outer member are swung outwardly. The coremember is then collapsed by withdrawing the rods 35 and tighteningmember D and loosening the planks 33 by turning the members 4:4 aspreviously described.

. by its use.

The mold is adapted for use in any form of concrete structures, and willenable any one flat or story of a dwelling house to be cast in onepiece. It will also enable the hollow walls to be constructed in thedwelling and if desired concrete walls, hollow or otherwise, for anypurpose may be formed Particular attention is called to the jointedcorner mold which'enables the wall molding elements to be swung aroundfrom the surface of the wall after casting.

It will be seen also that the cylindrical standards produced a partiallycylindrical surface at each corner and thus the interior of the roomwill have practically an unbroken surface and this minimizes a lodgmentof dust or dirt of any kind. If desirable a similar curved joint mightbe made between the floor and the wall. In addition to the advantage ofpreventing accumulation of dust this curved arrangement addssubstantially to the structure. It will also be noted that the cavityprovided by the use of the core mold adjacent to the window opening willconveniently accommodate sash weights. It is believed that the use ofthe present invention will enable a concrete house to be produced whichwill be proof against vermin, wind, frost, sound and fire.

As many changes could be made in the above construction and manyapparently widely different embodiments of my,invention, within thescope of the claims, constructed without departing from the spirit orscope thereof, it is intended that all matter contained in theaccompanying specification and drawings shall be interpreted asillustrative and not in a limiting sense.

What I claim as my invention is: a 1. In a concrete mold and incombination, a pair of outer corner members, means for adj ustablyconnecting said outer corner members together, means on each ofsaidouter corner members adapted to loosely receive a plurality of planks orthe like which are adapted to be used to mold the wall of the building,a pair of inner corner members, means for adjustably connecting theinner corner members together, and means on each of the inner cornermembers for holding a plurality of planks or the like, and a collapsiblecore member comprising a collapsible corner member and loosely held wallmolding members held by the collapsible corner members and cam means forexpanding the collapsible core member.

2. In a concrete mold and in combination,

. a pair of outer corner members, means for adjustably connecting thesame together, sockets on each of the outer corner members adapted toreceive a plurality of planks which are adapted to mold the outersurface of the wall of the building, a pair of inner corner members,means for adjustably connecting the inner corner members together,sockets on said inner corner members adapted to receive a plurality ofplanks for mold ing the inner walls of the building and a collapsiblecore member comprising a corner member having sockets to receive planksor the like and cam means for expanding the collapsible core member.

3. Ina concrete mold of the character described, a corner standardadapted to mold the corner, a socket member peripherally adjustablethereon and adapted to receive boards or the like which will mold thesurface of the wall.

-l. In a concrete mold, a corner post adapted to mold the corner and apair of angular adjustable socket members supported therefrom and wallmolding members held in the socket members.

5. In a concrete mold and in combination, a tubular standard adapted tomold corners and having cores at each end, socket members pivoted to thecores and including spaced plates and molding members held be tween thespaced plates.

6. In a concrete mold, a core member comprising a corner section formedwith parallel guldes, means for spreading the member for the coreextending through door or Window mold.

9. In a concrete mold, and in combination, a wall member, a collapsiblecore, a collapsible door or window mold and a spreading member for thecore extending through the door or window mold and serving to spread thecore mold and hold the Window or door mold together.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
